It turns out that gourds make pretty good Totoros, and Totoros make pretty good clocks, as this darling Totoro Gourd Clock by Etsy seller Gourd Geek makes very clear.

Gourds are a natural alternative to plastic that offer a smooth and clean finish while still being environmentally friendly. Because gourds grow naturally, their shapes are unique every time and, thus, items may not always be re-creatable depending on the shapes and sizes available.
